TITLE: GCN CIRCULAR NUMBER: 17476 SUBJECT: GRB 150219A: A long GRB detected by INTEGRAL DATE: 15/02/19 13:30:46 GMT FROM: Sandro Mereghetti at IASF/CNR S.Mereghetti (IASF-Milano), D.Gotz (CEA, Saclay), C.Ferrigno, E.Bozzo (ISDC, Versoix), and J.Borkowski (CAMK, Torun) on behalf of the IBAS Localization Team report: a gamma ray burst lasting about 60 s has been detected by IBAS in the IBIS/ISGRI data at 12:31:14 UT of February 19 The refined coordinates (J2000) are: R.A.= 271.2664 deg DEC.= -41.5849 deg with an uncertainty of 2 arcmin (90% c.l.). The burst had a peak flux of 1.4 counts/cm2/s (20-200 keV, 1-s integration time) and a fluence in the same energy range of about 4e-6 erg/cmq. A plot of the light curve will be posted at http://ibas.iasf-milano.inaf.it/IBAS_Results.html
